[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a raw material crushing device for PE granulation production, including a crusher body 1, a feeding port 2 and a discharging port 3. The feeding port 2 is opened on the upper side of the crusher body 1, the discharging port 3 is opened on the lower surface of the crusher body 1, and a collection mechanism 4 is provided on the lower side of the discharging port 3.

[0028] The collecting mechanism 4 includes a collecting box 41, a sliding block 42, a placement groove 43, and a pushing component 44. The collecting box 41 is located below the discharge port 3, the sliding block 42 is located below the collecting box 41, the placement groove 43 is opened on the upper surface of the sliding block 42, the lower surface of the collecting box 41 is in contact with the inner wall of the placement groove 43, and the pushing component 44 is located on the rear surface of the sliding block 42.

[0029] The pushing component 44 includes a support base 441, a first slide groove 442, and a first spring 443. The upper surface of the support base 441 is fixedly connected to the bottom of the crusher body 1. Two first slide grooves 442 are provided, and the two first slide grooves 442 are opened on the upper surface of the support base 441. The inner wall of the first slide groove 442 is slidably connected to the lower surface of the sliding block 42. Two first springs 443 are provided. The front end face of the two first springs 443 is fixedly connected to the rear surface of the sliding block 42, and the rear end face of the first spring 443 is fixedly connected to the inner wall of the first slide groove 442.

[0030] Specifically, the sliding block 42 moves along the first chute 442 to ensure that the collection box 41 moves accurately to the bottom of the discharge port 3, thus preventing PE raw materials from spilling. The design of the first spring 443 is such that when the collection box 41 is full, the first spring 443 automatically pushes the sliding block 42 back to the initial position, realizing unmanned operation of "filling-automatic exit".

[0031] Furthermore, the collection box 41 is placed inside the placement slot 43. Then, the sliding block 42 is pushed backward along the inner wall of the first sliding groove 442. The sliding block 42 compresses the first spring 443, causing the first spring 443 to generate elastic force. At the same time, the sliding block 42 drives the collection box 41 to move backward together until the collection box 41 moves directly below the discharge port 3. By pouring the PE raw material from the feed port 2, the PE raw material enters the crusher body 1 for crushing and flows out from the discharge port 3 into the collection box 41. When the collection box 41 has collected a large amount of crushed PE raw material, the first spring 443 releases its elastic force, pushing the sliding block 42 to move outward, and the operator can take out the collection box 41.

[0032] Example 2

[0033] In the second embodiment of this utility model, a clamping component 5 is provided on the upper side of the support base 441. The clamping component 5 includes a support block 51, a clamping groove 52, and a clamping block 53. The front surface of the support block 51 is fixedly connected to the rear surface of the sliding block 42. Two clamping grooves 52 are provided, and the two clamping grooves 52 are opened on the left and right sides of the support block 51. Two clamping blocks 53 are provided, and the outer surfaces of the two clamping blocks 53 are in contact with the inner walls of the clamping grooves 52.

[0034] The rear surface of the clamping block 53 is provided with a connecting component 6. There are two connecting components 6, including a connecting rod 61 and a second slide groove 62. The front end of the connecting rod 61 is fixedly connected to the rear surface of the clamping block 53. The second slide groove 62 is opened on the upper surface of the support base 441. The inner wall of the second slide groove 62 is slidably connected to the outer surface of the connecting rod 61.

[0035] Specifically, the operator only needs to push the sliding block 42 directly below the discharge port 3, and the clamping mechanism will automatically complete the positioning and locking, thereby quickly fixing the sliding block 42 and ensuring that the collection box 41 on the sliding block 42 remains stable during collection.

[0036] Furthermore, when the sliding block 42 moves the collection box 41 to directly below the discharge port 3, the sliding block 42 drives the support block 51 to press the inclined surface of the clamping block 53, so that the clamping block 53 moves outward along the inner wall of the second slide groove 62 through the connecting rod 61 until the clamping block 53 corresponds to the clamping groove 52, then the clamping block 53 can enter the interior of the clamping groove 52, indirectly fixing the sliding block 42.

[0037] Example 3

[0038] In the third embodiment of this utility model, a stroke component 7 is provided on the lower end face of the connecting rod 61. The stroke component 7 includes a stroke column 71, a stroke plate 72, and a stroke groove 73. Two stroke columns 71 are provided, and the upper end faces of the two stroke columns 71 are fixedly connected to the lower end face of the connecting rod 61. The stroke plate 72 is provided on the outer surface of the stroke column 71. Two stroke grooves 73 are provided, and the two stroke grooves 73 are opened on the upper surface of the stroke plate 72. The inner wall of the stroke groove 73 is slidably connected to the outer surface of the stroke column 71.

[0039] The inner wall of the support base 441 is provided with a third sliding groove 8, and the inner wall of the third sliding groove 8 is slidably connected to the lower surface of the stroke plate 72;

[0040] A drive assembly 9 is provided on the rear surface of the travel plate 72. The drive assembly 9 includes a pusher 91 and a second spring 92. The front end face of the pusher 91 is fixedly connected to the rear surface of the travel plate 72 and the pusher 91 passes through the rear surface of the support base 441. The second spring 92 is sleeved on the outer surface of the pusher 91. The front end face of the second spring 92 is fixedly connected to the rear surface of the support base 441 and the rear end face of the second spring 92 is fixedly connected to the front surface of the pusher 91.

[0041] Specifically, the operator only needs to push the pusher 91 forward, and the linear motion can be converted into the lateral displacement of the connecting rod 61 through the inclined surface of the stroke plate 72-stroke column 71. The clamping block 53 can completely disengage from the clamping groove 52 in a very short time, which improves the effect of taking out the collection box 41.

[0042] Furthermore, by pushing the pusher 91 forward, the pusher 91 can compress the second spring 92, causing the second spring 92 to generate elastic force. At the same time, the pusher 91 can push the stroke plate 72 to move forward along the inner wall of the third slide groove 8. The stroke plate 72 can press the outer surface of the stroke column 71 through the stroke groove 73 on its surface, causing the stroke column 71 to slide along the inner wall of the stroke groove 73. The stroke column 71 can drive the connecting rod 61 to move outward, causing the clamping block 53 to leave the inside of the clamping groove 52 and stop fixing the sliding block 42.

[0043] Working principle:

[0044] Place the collection box 41 inside the placement slot 43, and then push the sliding block 42 backward along the inner wall of the first slide groove 442. The sliding block 42 compresses the first spring 443, causing the first spring 443 to generate elastic force. At the same time, the sliding block 42 moves the collection box 41 backward together until the collection box 41 moves directly below the discharge port 3. When the sliding block 42 is about to move the collection box 41 directly below the discharge port 3, the sliding block 42 drives the support block 51 to compress the inclined surface of the clamping block 53, so that the clamping block 53 moves outward along the inner wall of the second slide groove 62 via the connecting rod 61. The outward movement of the connecting rod 61 indirectly pushes the pusher 91 forward, which compresses the second spring 92, causing the second spring 92 to generate elastic force until the clamping block 53 corresponds to the clamping groove 52. Then, the second spring 92 releases its elastic force, allowing the clamping block 53 to enter the clamping groove 52, thus indirectly fixing the sliding block 42. Then, by pouring PE raw material into the feed port 2, the PE raw material enters the crusher body 1 for crushing and flows out from the discharge port 3 into the collection box 41. When the collection box 41 collects a large amount of crushed PE raw material;

[0045] When the collection box 41 needs to be removed, the pusher 91 is pushed forward, which compresses the second spring 92, causing the second spring 92 to generate elastic force. At the same time, the pusher 91 can push the travel plate 72 to move forward along the inner wall of the third slide groove 8. The travel plate 72 can press the outer surface of the travel column 71 through the travel groove 73 on its surface, causing the travel column 71 to slide along the inner wall of the travel groove 73. The travel column 71 can drive the connecting rod 61 to move outward, causing the locking block 53 to leave the inside of the locking groove 52 and stop fixing the sliding block 42. At this time, the first spring 443 releases its elastic force, pushing the sliding block 42 to move outward, and the staff can remove the collection box 41.

[0046] In summary, the cooperation of the collection mechanism 4, clamping component 5, connecting component 6, stroke component 7, third chute 8, and pushing component 44 solves the problem of the device lacking collection of crushed raw materials, which leads to the splashing of crushed raw materials. These scattered PE fragments not only waste raw materials but also require workers to manually clean the ground after stopping the machine.
